Thanks for sharing the details, Norm! Try to repair File Permissions in the Excel Startup Folder
When the permissions get corrupted, Excel loads normally but blocks saving because it cannot write temporary files.
How to Fix It
Step 1 — Locate the Excel XLSTART folder
Copy and paste this in File Explorer:
%appdata%\Microsoft\Excel\XLSTART
Press Enter.
Step 2 — Fix File/Folder Permissions
Right-click inside the folder (on empty space)
Choose Properties
Go to Security
Click Edit
Select your Windows user account
Make sure these are checked:
- Read & execute
- List folder contents
- Read
- Write ← this one is the key
If Write is unchecked or greyed out → Excel cannot save.
Click Apply
Restart Excel
See if this helps. If you need further assistance just let me know.
Best regards,
Kimberly
